Fun Fact: An average kurzgesagt video takes about 6 months to 3 years of planning before being released. In this period, Kurzgesagt's team will contact different experts on the field concerned, fact check their drafts, video production typically runs up to 5 months, and voice overs. Kurzgesagt upholds to their mission to distribute educational and trusted videos. For this video here are the experts who helped with the topic: •Dr. Matthew Caplan-Illinois State University •Dr. Tenley Banik-Illinois State University •Dr. Michael Sussman •Dr. Lucas Kreuzer-Deutsches Zentrum für Luft- und Raumfahrt

16:30 You're partially right, yes the clouds and ash would trap the heat on Earth but the thing with global warming through CO2 and Methane is that those gasses dont reflect the sunlight allowing more heat to enter while not letting go of any. The ash would block sunlight which prevents the Earth from warming up during the "day" this makes it grow colder instead of warmer but I understand that it's kind of counter intuitive

15:52 nope. In a nutshell is right about that. Stratospheric aerosol injection works on the same principle. Aerosols in the clouds reflect sunlight and cool the earth. And it's a well known fact among climate scientists that volcanic eruptions can in fact cool the global temperature let alone the regional temperatures. one such example is the Mount Pinatubo eruption in 1991 in philippines caused a drop of 0.5 C in global temperatures,

I’ve heard scientists say a full moon has no effect on human behavior but they have likely never worked in an emergency department of a hospital during one. Let’s just say, shit gets weirder than usual.

Physics pedantry: The red giant phase won’t make the sun more “massive”, it will merely increase its circumference by a lot.

15:50 This is a bit wrong, we have documented the effect volcanoes have on the climate, and aerosols in general. They counteract the warming from greenhouse gases partially. Unlike aerosols, CO2-equivalents only grab infrared, thus not reflecting much.

15:57 The thing about Venus is that it has had billions of years to heat up. The Sun only barely heats the surface, as can be seen from the night and day sides being almost the same temperature. The Earth would not be in the same situation in the short term. Similar events have happened in real life, such as the 1816 year without a summer caused by the 1815 Tambora eruption.

this man is the most Gigachad looking physicist i ever seen... If i meet him irl i would think he is a PE teacher or an MMA enthusiastic

Dylan, please react to The Expanse, it's an amazing series that's one of the most scientifically accurate

This would be a great idea for a movie with the twist ending of everyone waiting for the moon to hit only for it to be destroyed before their eyes and met with a beautiful site rather than death. It would seem like an act of god for anyone who doesn’t understand the physics of it.

great vid, god i love the kurzgesagt channel, just gold nuggets of information

Happy belated birthday to my favorite aussie "science teacher" ! I come to learn but I stay for the good vibes 🙌😁

Great video with much useful insight. You're incorrect about the warming. Extended periods of vulcanism in earth's history have always led to cooling.

If only the directors or producers of Moofall just watched this video we might have had a cool movie 😂😂😂

to the point where you said at around 15:56 the earth would cool a lot and turn very snowy, it takes a while for those photons to actually get through and because the clouds would eventually dissipate this means that earth would never become like Venus because it takes too long and this is only very temporary.

What shape must a reflector be in order to reflect from any angle. Answer is square XD having a perfect right angle that's reflective off both sides will always give a reflection back to the observer. If you look at yourself in a cornered mirror, doesn't matter where you move, your reflection stays in the corner. The sum of the included angles will always end up being 180degrees.

"When Mercury's in Gatorade" 🤣🤣🤣 That completely got me off guard, I am totally using that the next time a Nurse tries to blame patient behavior on the full moon.

Happy birthday!! 🎉💖 Thank you for another fascinating video!

I haven't ever bought ANYTHING from any person's ads or their projects but I will support you with this soon
